Xin Qi · Journal of Beijing University of Chemical Technology · 2012
In this paper,we transform the Lorentz expression of Maxwell's equations to a four-dimensional tensor form by defining vector potential,scalar potential,the four-dimensional space vector and the electromagnetic field tensor.The result can better explain the movement of the electromagnetic field and verify the invariance of Maxwell's equations and the symmetry of the Lorentz expression of the four-dimensional tensor form.By listing actual examples we can verify the usefulness and effectiveness of the arithmetical method.At the same time,it can simplify the problem of a moving medium and provide some assistance in solving the movement problem,which demonstrates its superiority over the traditional form.
